Referring to the drawings by reference characters I have shown my invention as embodied in a time controlled valve device which is indicated generally at I0.

As shown the device I0 includes a hollow cylindrical body portion II having an integral cylindrical bottom portion I2 the axis of which is substantially perpendicular to the .axis of the body portion. The device i0 further includes a piston I3 slidable within the hollow body portion I I, and a cap portion I4 including a manually operated plug valve I5.

The bottom portion I2 has a iluid inlet aperapertures being adapted to "befconnected to a pipe line. `A ,wallf I8 having an `aperture :.IIl` with a raised rim 20 is disposed within the bottom por-` tion I2, diagonal walls 2| and 22 being connected y thereto asshown in Fig. 3.

"A'dash-pot' assembly 34 is shownlocatedbelow the aperture I9 and includes a hollow cylinder y 35with'a closedlower nd136 vand an upper reduced threaded portion 31 engaging an apertureV 38 in a depending hub 39 on thebottom I2,'pack ing 40 being' disposed therebetween. VvA piston 4I is disposed within the cylinder 35 and has a lower central recess 42 accommodating a spring 43.' and an iup-per boss v44 adapted to engage the lowerk end of the boss`30 Von-the piston I3. A

AThe cap I41is`secured to the body portion Il y by cap screws 41 and includes an upstanding hub 48 having a tapered bore 48' engaged by the plug valve I54 which Yis held therein by a retaining collar 49'engaging a threaded portion-49 of the bore 48" packing 50 beingidisposed between the collar and the valve.r` A 'pair of opposed radial arms 5|" and-SZ'are'disposed' on' the top face of the cap 'I4 'and have conduits 53 -and 54 therein respectively;`

The conduit 54 communicates'. with a `vertical conduit`55 opening to thel atmosphere Awhile .the

conduiti53communicates with a vertical :conduit 55 and may include a screen 56 which leads from vthe lower portion of the hollow cylindrical body portion Il. `Asr shown in Fig. 1 the conduit 54 is on a somewhat lower level than the conduit 53.k A conduit 51,- (Fig. 3) vthreadedly engages an aperture 58 communicating with the interior of the4 Valve device I asat 59. The conduitr 51 may be Y closed by a suitable valve 59 such as a` solenoid Operatedvalve. f

The plug, `valve I5 hasl an axial conduit- 60 opening through the underface thereof and at its upper end communicating with a plurality of radial coplanar conduits 6I on the same level as indicating the positions ofthe various radial conduits in the plug valve I5. In use the device I is connected in a pipe line,

as for instance, a sprinkler system, it beingA desirable to operate the sprinklers for a certain pre- The plug .valve l The conduit I I 0 is at a somewhat lower level than determined period of time. is rotated so that the radial conduit 62 communicates with' the conduit54 thus affording free passage between the interior ofthe body portion .and the atmosphere. ATheiiuid entering the inlet aperture I6 .urges thepiston I3 upwardly discharging fluid in the upper part of the hollow body portion I I via theconduits Ii0y 54 and 55 and lling the chamber below thepi'ston I3. This operation opens the aperture I9 allowing free passage offluid'through the outlet aperture I 'I.

. Fluid will n'ow flow up the conduit 56 and slowly dischargev into the hollow body Yportion II above the piston I3 via thegconduits 53, 6| and 60, and allow the piston I3 to drop until the aperture .I9 is againl closed stopping the uid iiow. Near the end of thek downward stroke the flowis slowlydecreased bythe action of the tapered sleeve 32, while the nal movement of the piston is retardedbythe action of the dash-pot, 34. 'Ihis slow; checking of the Vfluid owvis desirable to eliminate the dangers -of a "water hammer effeet'. 1, E If it is desired to control the'valve devicei I0 remotely thepreliminary discharge of the iiuid above the piston maybe effected by opening the solenoid operated valve (not shown) on the-conduit 5'I by closing a switch in the solenoid circuit. This may be done manually or by a suitable yclock device; It :will be understood that 4the capacity of theA conduitsI 5J and 59 must exceedthe capacity of the largest conduit 6| in order to *fully raise the piston I3. In Figs. 7,'8, 9 and 10 I have shown a modcation of my valve device which'I have indicated A generally at- 80., Y* As shown the valve device 80 includes, a hollow cylindrical body portion 8| threadedlyV engaging an upper cap 82 and a lower capY 83'; The device 80 further includes a hollow piston 84slidab1e within the body portion 8|:

. The lower cap 83 has an inlet aperture 85 and anoutlet aperture 86 and is provided 'with a wall 8`| with an aperture 88 therein, diagonal walls 89 being disposed as shown in Fig. 7; A rod 90 is rigidly connected to the cap 83 as at 9| and extends upwardlythrough the aperture 88.

The piston 84 includes a central cored member 92`with an enlarged lower portion 93 having a recessin the under face vthereof containing a 4 packing ring 94 engageable; to close the aperture 88. 'A lower plate 95 and upper plate 96 are secured to thevcore member 92 asby welding, the two plates forming a chamber 9.1. The upper plate 96 carries .apacking cup 98ysecuied by a plate 99 and a nut |00. The core member 92 is provided with a central bore |0| slidable on the rod 90 and having a radial aperture I 02 at its upper end communicating with the chamber 9I. A spring |03 normally urges the piston 84 downwardly.

The upper cap 82 includes an inwardly depending hub |04 having a bore |05 the upper end of which is tapered and engaged by a manually operated plug valve |06 h eld therein by a retaining ring I0'I threadedly engaging the bore of an upstanding hub |08 coaxial with the hub |04. Radial Yconduits |09 and I I0 communicate at their 'inner ends with the tapered bore |05 and at their outer ends with vertical conduits and ||2 respectively, the conduit I|2 communicating with the atmosphere and the conduit communicatingwith the lower part of the hollow body portion 8| below the piston 84 as shown in Fig. 10.

'the conduit |09. i

The plug valve |08 has an axial conduit |I3 whichat. its upper end connects with a radial conduit I4 at the level Tof the conduit |09, and a radial conduit ||5 at the level of the conduit I|0.v A peripheral groove .|I6, tapered in both width and depth as shown in Figs. 8 and 9 is provided on-the plug valve |06 at the level of the conduit |09.

The device 80 is actuated in a manner similar to that described. for the device I0, the piston 84 being iirst carried upwardly opening the aperture 88 and then is .urged slowly downwardly by the spring |03 fluid entering above the piston Via the co-nduits |09, |,|3 and the groove I|6. It will be seen that the tapered4 groove ||6 provides means for' adjusting the flow of iluid and consequently the timing of thevvalve. The piston is retarded towards the end of the stroke yby the action off,y the rod 90 forcing fluid from the bore llthrough the' 'aperture |02 into the interior of thepiston 84. f z x In Fig. 10 I have shown a tubular extension |20 on thev device 80, at its lower end engaging the hub |08, so that the device 80 may be placed conveniently below the surface of the ground but leaving the operating parts exposed. I

In Figs. 1l, 12 and `13 I have Vshown animproved plug valve I5 which may be employed in placenf the plug I5 'and wherein the radial con- `duits 6| are all the same size, metering disks v conduits 6| `The plug 5 includes a conduit 62 vwhich functions as does `the conduit 62.
